MAK,

Since the '922 is in full production i wondered about the "generality" of the advise to implement a '2051 (which is how i would do it but maybe not generally advise).

Finding the price to be $6.00 vrs Digikey's $2.72 for the '2051 i think the advise is very good (as long as your effort can be amortized in education or aggregate program expense).

regards,
p
